In the self‑storage industry, your facility’s roof is one of the most critical assets. A well‑maintained metal roof can keep your units dry, secure, and energy efficient. But over time, corrosion, UV exposure, thermal cycling and general wear can compromise performance — especially on metal roofs. That’s where a quality roof coating comes into play. At A&O Roofing Solutions, we specialize in commercial roofing for metal buildings, and we see how a properly applied roof coating can deliver real savings, extended life and improved tenant satisfaction.
In this article we’ll cover:

Why roof coatings make sense for metal roofs in storage facilities

What key benefits you’ll see (cost, performance, maintenance)
-
Typical pricing in the Dallas market, so you can budget smart

Why Roof Coatings for Metal Roofs (Especially in Storage Facilities)
Metal roofs are common in public storage facilities for good reason — they’re durable, relatively straightforward to install, and can be cost‑effective. But metal doesn’t mean “no maintenance.” Over time you may face:
-
Corrosion or oxidation at fasteners, seams or cut edges
-
Thermal expansion/contraction that stresses seams or fasteners
-
UV degradation of finishes, leading to fading, chalking, or loss of reflectivity
-
Potential leakage at penetrations, seams or damaged areas
-
Heat gain in summer, increasing HVAC or climate‐control costs in units
Applying a quality roof coating over an existing metal roof addresses many of these issues without the higher cost and disruption of a full roof replacement. For a storage facility, that can translate to:
-
Extended roof life — a coating can act as a sacrificial protective layer, slowing deterioration.
-
Improved energy/thermal performance — many coatings reflect more solar energy, reducing heat load.
-
Reduced maintenance / repair frequency — fewer leaks, fewer patch jobs, better durability.
-
Faster installation, less downtime — because you don’t remove the roof, you can often keep operations running.
-
Lower lifecycle cost — the upfront cost of coating is typically far less than a full roof replacement, yet gains many of the same benefits.
For public storage facilities, where you may have large metal roof areas, many seams/penetrations, and a need for long‑term predictable costs, a roof coating is a compelling investment.
Key Benefits in Detail
Let’s break down the major benefits you’ll realize:
1. Life Extension of Roof Asset
A roof coating applied properly acts as a “second skin” — it protects the metal substrate from direct UV, weathering, and corrosion. That means you may be able to push out a full roof replacement by several years, sometimes decades depending on conditions and coating system.
2. Energy & Thermal Savings
In Texas and specifically the Dallas market, summer heat is a major factor. A reflective coating on a metal roof helps reduce solar absorption, which in turn can lower the temperature inside the building and reduce HVAC / climate‑control load. That is particularly relevant if your storage units are climate‑controlled.
3. Reduced Leak Risk & Maintenance Costs
When you coat the roof, you’re sealing many of the weaker points: seams, fasteners, flashings, and penetrations. That means fewer water intrusion events, fewer reactive repair jobs, less potential damage to stored goods, and fewer tenant complaints. Over time, that lowers your maintenance burden.
4. Minimal Disruption & Quicker ROI
Compared to a full roof tear‑off and replacement, coating a metal roof is less disruptive to the facility operations. This means less risk of downtime, less impact on tenants, and a faster return on investment in terms of cost savings or avoided costs.
5. Improved Asset Value & Tenant Perception
A well‑maintained roof adds to the curb‑appeal and asset value of your facility. Tenants notice when a facility is in top condition — fewer leaks, fewer issues. For you as the owner/operator, it can also help with long‑term resale value or financing.
Typical Cost in Dallas, Texas
One major question: What should you budget?
Based on recent data for the Dallas / DFW market:
-
A national guideline for coating a metal roof is about $1.50 to $3 per square foot for materials & installation. Angi+2HomeGuide+2
-
In the Dallas market specifically, elastomeric roof coating projects for metal roofs range roughly around $1,159 to $2,085 for around ~1,282 sq ft (which equates to roughly $0.90 to $1.60 per sq ft in those smaller projects). Homeyou
-
Another source lists metal roof coating cost national range for metal & aluminum roofs at $0.50 – $4.00 per sq ft depending on prep and system. HomeGuide
What we recommend budgeting for a public‑storage metal roof in Dallas:
Given the large area of typical storage facility roofs and factoring in prep work, penetrations, fasteners, flashings, slope, access and climate‑related factors, a realistic budget range might be $1.75 to $2.50 per square foot for a high‑quality coating job.
For example:
-
Facility with 50,000 sq ft of metal roof: at $2.00/sq ft → ~$100,000.
-
Facility with 30,000 sq ft: at $2.25/sq ft → ~$67,500.
Of course, pricing will vary with roof condition, the type of coating selected, number of layers, access challenges, and how much repair is needed before coating.
Why this higher budget?
-
Larger commercial/industrial roofs often require more prep (rust treatment, fastener replacement, seam repair).
-
Penetrations and penetrative flashings typical in a storage facility increase labor.
-
Commercial coatings may require thicker application or premium products given harsh exposure and long‑term performance requirements.
-
The ROI on large metal roofs justifies premium performance and long life.

Considerations Before You Proceed
Before you commit, here are some key items to verify and plan for:
-
Roof condition & fastener integrity: Ensure the metal roof substrate is still sound, fasteners are secure (or replaced), rust is treated, and seams are intact. A coating cannot “fix” a badly deteriorated substrate; it protects a solid base.
-
Surface preparation: Cleaning, rust treatment, priming, and repair of flashings/seams are critical. Skipping or minimizing prep undermines performance and longevity.
-
Coating type & manufacturer warranty: Choose a coating suited for metal roofs (elastomeric acrylic, silicone, polyurethane) and check what the manufacturer and contractor warranty cover.
-
Reflectivity / energy performance: If you have climate‑controlled units, ask about daytime heat reduction and how the coating affects roof surface temperature.
-
Drainage / slope / ponding: Even metal roofs need proper drainage. Coatings can help protect but won’t solve major ponding issues.
-
Roof access and disruption plan: Plan for how the coating work will be done with minimal tenant disruption, and how weather or access may impact schedule.
-
Lifecycle costs & maintenance: Think beyond the initial coating — budget for periodic inspections, minor touch‑ups, and future recoating. The goal is minimizing total cost of ownership.
